PHP is my first language. As many young developers that want to start do some server-side stuff, they stub upon PHP. I started PHP as everyone doing it without classes and procedurial. From the outside looks like an not so good language but when mastered can be as good as other trendy server-side languages.
Now I use PHP mostly with Laravel as it covers the most of the requirements of the things I've done in the past and currently doing.

Laravel is my framework of choice in PHP. Ease, Elegant and yet powerful. I've done most of my projects on Laravel so I'm looking forward to do more with this tool in the future.
Currently working with 2 project on Laravel.

React is a real life saver tool when coupled with Redux. As a developer that don't really likes DOM based programming, react gives another look on how you can switch the classical javascript way of doing things.
Currently doing my first project on React and will use it on every other project that is SPA.

As a Web Developer, I can't really keep up with Native Mobile applications. It's hard to keep up with things in javascript, so Java/Swift native development is even harder to keep up with. React Native is my tool of choice when doing Native mobile applications.

Css preprocessors are a must today. I think Sass is a sane choice of tool and makes your code easier to work with. I try to couple Sass with atomic design and always keep the code clean to write and read. Do you have a big Sass project that you want to re-organise, ping me.

AWS (for short), is powerful cloud provider. Contrary to common belief, it is not so hard to use. You can start small with EC2 machines and can scale up to everything imaginable on server infrastructure.

Docker is an interesting tech. Thinking of dev/production on a completely different way. I've only used Docker for learning purposes and hand't had the opportunity to use it on a big product. Had done some experimentation just for testing purposes but not real deployment on a real project because the use-case of Docker is specific for big teams and big products.
I think is interesting and looking forward to use it on the future.

Server management is a fun topic when want to do something else than developing. Also it's good to have knowledge on this topic because as a Back-end developer you have to know how things run on the server, what are the common pitfalls etc, etc.
Without knowing managing Servers and work with them, I couldn't work properly with PHP.

Everybody that has done a bit of web has used jQuery in a way or another. jQuery is nice on little project but I prefer to use vanilla JS when possible as this tool adds a lot of page load. Had fun when first started to learn Javascript, but right now wouldn't be my first tool of choice.
